In the given figure L, M and N are mid point of the sides PQ, PR and QR respectively of `DeltaPQR`. If PQ = 4.4 cm, QR = 5.6 cm and PR = 4.8 cm then find the perimeter of `DeltaLMN`.

In DeltaPQR , PQ = 5 cm, QR= 12 cm, and PR = 13 cm, then PQR is

In the figure, M and N are the midpoints of sides PQ and PR respectively . If MN =6 cm then find QR. State your reason .

In the adjoining figure, S and T are points on the sides PQ and PR respectively of DeltaPQR such that PT=2cm, TR=4 cm and ST is parallel to QR. Find the ratio of the ares of Delta PST and Delta PQR .
